Hm, I'm not able to add a key to the system keyring that is signed by a
key on either the system or the IMA MOK keyrings. The system keyring
seems to be "locked". A key that is signed by either a key on the
system or the IMA MOK keyring can be added to the IMA keyring.
keyctl show %keyring:.system_keyring
Keyring
973688077 ---lswrv 0 0 keyring: .system_keyring
evmctl import m1-cert-signed.der 973688077
add_key failed
errno: Permission denied (13)
